    [0003]BACKGROUND OF THE INVENTION
    [0004]1. Field of the Invention
    [0005]The invention relates to a sealing strand for adhesive attachment to a vehicle body, particularly to a body flange projecting away from the vehicle body.
    [0006]2. Description of the Related Art
    [0007]It is known that seals on vehicle, for example door seals, are formed by means of sealing strands that can be set onto a flange projecting away from the vehicle body, using a U-shaped attachment section. Alternatively, the seal is adhesively attached to the flange or to a body region adjacent to the flange.
    [0008]SUMMARY OF THE INVENTION
    [0009]The invention is based on the task of creating a new sealing strand intended for adhesive attachment to the vehicle body, which strand can be conveniently mounted on the vehicle.
    [0010]The sealing strand according to the invention that accomplishes this task is characterized by means for tacking the sealing strand to the vehicle body.
    [0011]It is advantageous that such a sealing strand can be affixed on the vehicle body, before being adhesively attached, so that it is held on its own there and, in particular, is sufficiently fixed in place in a starting position for the adhesive attachment process. During the adhesive attachment process, it is not necessary to exert any holding forces while orienting the sealing strand to be adhesively attached.
    [0012]In a preferred embodiment of the invention, the stated means are means for tacking the sealing strand to the body flange. In particular, the stated means have devices for the production of a clamping connection of the sealing strand to the body flange.
    [0013]It is practical if the sealing strand can be set onto the body flange with the production of a clamping connection transverse to the longitudinal axis of the strand. In particular, the devices for the production of the clamping connection have a clamping shank disposed in clip-type manner relative to an adhesive surface of the sealing strand, for this purpose. It is advantageous if the body flange is automatically clamped in between the adhesive surface and the clamping shank when the sealing strand is set onto the body flange, with the production of a holding force for the sealing strand. It is understood that in this state, the adhesive surface does not yet act in adhesive manner, and that a double-sided adhesive tape that might be used for the adhesive attachment is still covered by a protective film.
    [0014]It is practical if the sealing strand has a stop that is decisive for the desired tacking position, particularly for the starting position of the adhesive attachment process, against which stop the free end of the body flange preferably lies.
    [0015]In a further embodiment of the invention, the stated clamping shank is connected with the remainder of the sealing strand by way of a crosspiece-like bridge that forms a planned breaking point. It is advantageous that if necessary, the clamping shank can be pulled off after complete installation of the sealing strand, by tearing the planned breaking point apart.
    [0016]In a further embodiment of the invention, the clamping shank can be connected with a covering lip of the sealing strand that extends in an arc over the clamping surface, whereby preferably, the clamping shank can be torn off from the adhesively attached sealing strand, with orientation of the covering lip in a covering position.
    [0017]Preferably, a double-sided adhesive tape having a protective film, which can be pulled off using the application device stated initially, if necessary, serves for the adhesive attachment.
    [0018]BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in greater detail in the following, using exemplary embodiments and the attached drawings that relate to these exemplary embodiments. These show: FIG. 1 a first exemplary embodiment of a sealing strand according to the invention, having a clamping shank demonstrating an angular deflection, FIG. 2 an exemplary embodiment of a sealing strand according to the invention, having a clamping shank that can be torn off from a covering lip, FIG. 3 an exemplary embodiment of a sealing strand according to the invention, having a covering lip that simultaneously forms a clamping shank, FIG. 4 a further exemplary embodiment of a sealing strand according to the invention, having a clamping shank that can be torn off, FIG. 5 a representation that explains the installation of the sealing strands according to the invention.
    [0019]DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
    [0020]A sealing strand having a sealing section 1 and an attachment section 2 consisting or a harder elastomer material than the sealing section serves for forming a seal on a vehicle door and is intended to be adhesively attached to a body flange 3 that runs around the circumference of a door opening. The adhesive attachment of the attachment section 2 to the flange 3 takes place using a double-sided adhesive tape 4 adhesively attached to an adhesive surface 18 of the attachment section 2 , which tape has a protective film 12 .
    [0021]A covering lip 5 that runs in an arc over the attachment section, angled away from the latter, extends from the attachment section 2 ; this lip lies against the edge of a body part 6 in the completely installed status of the sealing strand, and covers a gap between the body flange 3 and the body part 6 .
    [0022]A projection 7 at the foot of the covering lip 5 forms a stop for the free end of the body flange 3 .
    [0023]A shank 8 having an angular deflection 15 extends from the covering lip 5 , whereby the shank 8 engages on the body flange 3 opposite the attachment section 2 or the adhesive tape 4 in the manner of a pliers shank.
    [0024]Furthermore, a rubber string 9 having an embedded tear-resistant thread 10 is connected with the covering lip 5 , whereby the rubber string is connected with the covering lip 5 by way of a crosspiece 11 that forms a planned breaking point.
    [0025]To install the sealing strand shown in FIG. 1 , with adhesive attachment to the body flange 3 by means of the adhesive tape 4 , the sealing strand is at first only tacked onto the vehicle body and, for this purpose, set onto the body flange 3 until the free end of the body flange 3 makes contact with the projection 7 . The shank 8 connected with the covering lip 5 ensures clamping of the sealing strand to the body flange 3 , the side of which, facing the attachment section 2 , lies against the adhesive tape 4 . The adhesive tape 4 is still covered with the protective film 12 in this tacked state.
    [0026]The sealing strand is now in a starting position for adhesive attachment to the body flange 3 , using an application device 13 reproduced schematically in FIG. 5 . A press-down pressure according to arrow 14 , which ensures adhesive attachment, is produced by way of the application device 13 , with the sealing section 1 of the sealing strand being folded together. If necessary, production of the press-down pressure takes place continuously by means of a roller or a slide shoe. In any case, the application device 13 comprises means for pulling the protective film 12 off from the adhesive tape 4 before the adhesive attachment process, according to the arrow 19 , whereby these means can comprise a pull-off roller (not shown) that precedes the application device, for example.
    [0027]After the sealing strand has been adhesively attached to the body flange 3 , the rubber string 9 is pulled off, in a final work step, with continuous tearing of the crosspiece 11 that is configured as a planned breaking point, and the covering lip 5 is thereby brought into the planned veneering position, with contact against the body part 6 . If necessary, pulling the rubber string 9 off takes place automatically, using the application device 13 , for example together with pulling off the protective film 12 .
    [0028]In the following exemplary embodiments, shown in FIGS. 2 to 4 , the same parts or parts having the same effect are indicated with the same reference number as in FIG. 1 , whereby the letter a, b or c is appended to the reference number in question.
    [0029]In the exemplary embodiment of FIG. 2 , a shank 8 a that projects away from a covering lip 5 a , which shank serves for a clamping connection of the sealing strand shown with a body flange 3 , simultaneously forms an installation string for positioning of the covering lip 5 a in a covering position. Accordingly, a tear-resistant thread 10 a has been set into the shank 8 a , and the shank stands in connection with the covering lip 5 a by way of a crosspiece 11 a . A projection 16 that projects away from the shank 8 a supports the transfer of a clamping force to the body flange 3 . Pulling the shank 8 a off takes place, if necessary, by way of a pull-off device that follows the application device 13 .
    [0030]In the exemplary embodiment shown in FIG. 3 , a covering lip 5 a itself forms a clamping shank that tacks the sealing strand onto the flange 3 . Using a tear-off string 9 b , the covering lip 5 b can be brought into its intended position after the sealing strand has been adhesively attached.
    [0031]In a sealing strand shown in FIG. 4 , an attachment section 2 c is connected with two sealing sections 1 c and 1 c ′, and has an angular deflection 17 that forms a stop for the free end of a body flange 3 c . A shank 8 c that projects away from the stop, which shank serves for clamping the sealing strand to the body flange 3 c , is connected with the angular deflection 17 by way of a crosspiece 11 c that forms the planned breaking point, and a tear-resistant thread 10 a for pulling the shank 8 a off after installation of the sealing strand has taken place is formed in the shank 8 a.
